Simple answer, do not restore a DC from a backup if another DC is running.

If you must restore a domain from a backup, only use the Samba provided 
tools (note 'domain' and not 'DC').

Demote your dead DC on the running DC. Repair or replace your dead DC, 
remove the smb.conf and any .tdb and .ldb files from /var/lib/samba (or 
wherever samba is), then rejoin as a new DC.
